Answer:
Explanation:
So, the formula for the compound should be:
[tex]XCl_{6}[/tex]
Now we assume that we have 1 mol of substance, so we can make calculations to know the molar mass of element X, as follows:
[tex]M_{Cl}=35.45g/mol\\[/tex]
So we have that 6 moles weight 212.7g, and we can make a rule of three to know the weight of compound X:
[tex]212.7g\rightarrow 86.9\%\\x\rightarrow 13.1\%\\\\x=\frac{212.7g*13.1}{86.9} =32.06g[/tex]
As we used 1 mol, we know that the molar mass is 32.06g/mol
So the element has a molar mass of 32.06 g/mol and an oxidation state of +6, with this information, we can assure that the element X is sulfur, so the compound is [tex]SCl_{6}[/tex]
